CAR STARTER AND BRAKE.

SPECIFICATION forming part of Letters Patent No. 414,183, dated November 5, 1889.

Application filed .Tuly 23, 1889.

Serial No. 318,354. (No model.)

To @ZZ whom it may concern:

Be it known that I, NVENDELL A. BAKKER, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Gar Starter and Brake, of which the following is a specification.

My invention relates to improvements in car starters and brakes and it consists in certain novel features hereinafter described and l claimed.

In the accompanying drawings, Figure l is a vertical longitudin al. section of my improved device, showing' it in position on a caraxle. Fig. 2 is an end elevation of a part of the de vice. Figs. 3 and 4 are detail views.

The axleAis of the usual construction, and the car-wheels B are secured thereto in the usual manner. Near each end of the axle I loosely mount thereon the caps C, having out wardly-projecting annular iianges D, and around the axles, between the said caps, I arrange the coiled springs E, which have their ends secured to the said caps. Adjacent to the said caps, and fitting within the annular flanges of the sa1ne,l rigidly secure to the axle the friction-pulleys F, and these frictionpulleys are enga-ged by dogs G, which are piv-l oted in diametrically-opposite recesses H of the said caps, and are held normally in contact with the edges of the said pulleys by the springs I, secured within the said recesses and bearing on the dogs.

Operating-disks G are loosely mounted on the axle adjacent to the friction-pulleys, and they are provided with lugs or shoulders J, which are adapted to impinge against arms K, formed integral with and extending inward from the dogs G, as shown. These operating-disks are controlled by the levers L, loosely mounted on the axle adjacent to the disks, and the pawls M, pivoted to the lower ends of said levers and adapted to bind against the edges of the disks, the said pawls being connected by a rod N, which extends forward to the braledever.

Around the caps C,I arrange the frictional clamping-bands O, which have their inner ends P secured tothe supporting-frame of the car and have their outer ends connected by the links Q with a lever R, the said lever R being connected to the brake-lever by a connectinguod S. The brakelever is connected with these frictional clamping-bands at one side of the car and with the pawls M at the opposite side, and a second brake-level', arranged at the other end of the car, is connected with the remaining clamping-bands and pawls, so that the car may be driven in either direction without being turned completely around.

The brake is applied by throwing thebraken lever in the proper direction to draw on the `clamping-bands O and cause them to bind around the caps, as will be readily understood, and the rotation of said caps will thus be stopped, while the friction-pulley will continue to move under the dogs or pawls, which will drag thereon and stop the car. IVhen the cap is stopped, of course the spring secured thereto is held stationary; but the cap and spring at the other side of the ear will continue to rotate, and the spring will thus be wound. Upon moving the brake-lever so as to release the clamping-bands from the caps the spring at once unwinds and imparts motion to the cap, which -Will carry the dogs into engagement with the friction-pulley, so that the motion of the cap will be communicated directly to said pulley and through the pulley to the axle, and the car thereby started.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. The car starter and brake having the caps, the clamping-bands passing around the same, the brake-lever, and connections between the said lever and the bands, as set forth.

2. A caistarter comprising the friction-pulleys rigidly secured to the axle at the ends of the same, the caps loosely mounted on the axle and carrying dogs adapted to bind on the pulleys, and the springs coiled around the axle, extending between the caps, and having their ends secured to the same, as set forth.

3. The car-starter consisting of the pulleys secured rigidly on the axle, the caps mounted loosely on the axle, the springs between the said caps, the dogs pivoted to the said caps and adapted to bind on the pulleys, and having integral inwardlyextending arms, the

IOO

shoulders adapted\to engage the said arms, the levers loosely mounted upon the axle, and the pawls pivoted to said levers and adapted to engage the disks, as set forth.

In testimony that I claim the foregoingias my own I have hereto affixed my 4sig/nature inpresenoe of two Witnesses.
